CULINARY BOILER.

SPECIFICATION forming part of Letters Patent No. 285,351, dated September 18, 1883.

Application filed May 26, 1883.

d is a stiff bearing on top of the cover A,

To all whom it may concern.-

Be it known that I, WILLIAM S. FIOKETT, of Rochester, Monroe county, New York, have invented a certain new and useful Improvement in Culinary Boilers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which Figure 1 is a central vertical section of the boiler. Fig. 2 is a plan of a portion of the inverted cover A, looking on the under side. Fig. 3 is a plan of the top of the tube 0, show ing the locking device. Fig. 4 is a section of tube 0, looking upward from line as m. Fig. 5 is an edge elevation of the locking-key.

My invention relates to that class of culinary boilers or steamers adapted to rest on top of an ordinary pot or kettle in which water is placed for the purpose of producing steam by which the cooking is done.

It consists in the combination of the inverted cover the open-topped receptacle, the fastening device, and a disk forming a steamspace in the top of the cover and above the receptacle, as will be more fully set forth.

It further consists in the peculiar construction and arrangement of the fastening, as will be fully described. I

In the drawings, A shows the inverted cover or support,- which is simply a dish in the form of a basin, which rests upon and covers the top of the ordinary pot or kettle, B.

D is a disk resting in the bottom of the cover, being struck down, so as to form a steamspace, a, which communicates with the steamspace below by small openings 12 b. In the center is a circular flange, c, which forms a partition, cutting off any escape of the steam at the center and confining it in the steam-space. As fast as the steam is condensed the water drips back through the openings 7) 1) into the pot or kettle.

E is the open-topped receptacle which receives the substance to be cooked. It is preferably of conical form, and in the center it has a conical tube, 0, open at both ends, by which the steam escapes upward through an opening in the top of the cover A. This steam is prevented from mingling with the steam in the steam-space a by the partition 0, before described.

having a circular hole in its center and a raised flange at its top.

f is a bearing on top of the tube 0, having also a circular hole, 9, in its center, with two radial slots, 9 opening therefrom, as shown in Figs. 3 and 4, which show top and bottom views of the bearing. On the under side of this hearing are also two curved camways or eccentries, h h, which gradually rise from one end to the other on a curved incline.

G is a flat locking-key, having aloop, i, at the top, two shoulders, k k, which rest on top of the bearingd on the cover, and two reverse shoulders, Z Z, which rest.under the camways h h. WVhen the key is inserted, the shoulders Z Z pass down through the slots 9 g, and when they reach the bottom, by turning the key, said shoulders turn under the camways, and by gradually riding up on said camways they draw the open top of the receptacle E up against the disk D, thus securing the parts together, and making the receptacle so tight that none of the exterior steam can enter, (since it is not under pressure,) but at the same time allowing the escape of such steam as is generated inside of the receptacle when sufficient pressure is attained. Thus the cooking may be. done, retaining all the aroma, and, if de sired, other food or materials may be cooked in the pot below without tainting the contents of the receptacle. The cooking is greatly facilitated by the interior tube, 0, which allows heat to enter directly through the interior of the substance being cooked. Other and different fastening devices may be used, if desired, as it is only necessary to use some device to lock the parts firmly together and allow ready separation. The device G shown furnishesa loop for carrying-the device when necessary.

The construction of this cooker is such that the steam surrounds the sides and the top of the receptacle that contains the food, and also passes centrally up through it. The steamspace a at the top is of importance in thus applying heat at the top and preventing the chilling that would occur inside the receptacle if a single thickness alone were used. By making the cover and the receptacle separate, the latter can be filled and emptiedwithout trouble, and by using a locking device they can be fastened together, so that the food is closed against entrance of the outside steam.

If desired, one or moreslnall holes, 8 8, may be made in the top of the cover A, to allow escape of air as the steam fills the space a.

Having described my invention, I clain1 1. In a culinary boiler, the combination of the inverted cover A, the disk D, forming a steam-space at the top of the cover, and cut off from the center by a partition, 0, the opentopped receptacle E, provided with the inte rior tube, 0, and a locking device, G, for securing the receptacle to the cover, a central opening or passage being left in the cover above the tube 0, as shown and described, and for the purpose specified.

2. The combination of the bearing (1 on top of the cover, the bearing f on top of the tube 0, provided on its under side with camways h 71 and the key G, provided with shoulders 76 7c at the top, resting on the bearing d, and with shoulders Z l at the bottom, resting under the camways h h, as shown and described, and for the purpose specified.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
